AA has an auction going right now for what is being called a pre-war Official Police. It's Item# 7439931. Thing is, it has a windage adjustable rear sight. The top strap doesn't have a sight groove, so it's not a conversion from a fixed sighted gun. The barrel is marked Official Police, and has the usual for it's time front sight for a fixed sighted gun. What say you all? Did someone screw an OP barrel onto an old Officer's Model, or did Colt make this gun in this configuration?
